Vat dyes, also known as indigo dyes, are a class of dyes with a long history and excellent performance. They are insoluble in water but can be reduced to a soluble form in an alkaline reducing solution, which is then used to dye fabrics. After dyeing, oxidation is carried out to restore the dye to its original insoluble form and fix it on the fiber.
High Fastness: Vat dyes have excellent fastness to light, washing, and rubbing. Fabrics dyed with vat dyes can maintain their color for a long time even after repeated washing and exposure to sunlight.
Rich Color: They can provide a wide range of vivid colors, including deep and bright shades. The color gamut is very rich, meeting various color needs in the textile industry.
Good Environmental Performance: Compared with some other dyes, vat dyes have relatively low environmental impact. They do not contain harmful substances such as heavy metals and formaldehyde, which is in line with the requirements of environmental protection.
Cellulosic Fibers: Mainly used for dyeing cotton, linen, and viscose fibers. They can form a strong bond with these fibers, resulting in excellent dyeing effects.
Printing: Also widely used in the printing process of textiles. They can produce clear and detailed patterns with high color fastness.
Q: How to store vat dyes?
A: Vat dyes should be stored in a cool, dry place, away from direct sunlight and heat sources. Keep them in a sealed container to prevent moisture and air from affecting their quality.
Q: Are vat dyes difficult to use?
A: The dyeing process of vat dyes requires certain technical skills and equipment. However, with proper training and operation, it is not difficult to master. And the excellent dyeing effect is worth the effort.
